What is a Calories Burned?

A calories burned calculator estimates how much energy you expend during physical activity based on your body weight, the type of activity, and how long you perform it. It uses MET (Metabolic Equivalent of Task) values — a standardised, research-validated system that quantifies the energy cost of activities relative to rest — to produce an accurate calorie burn estimate without requiring specialised equipment.

The formula is simple but powerful: Calories = MET × weight (kg) × time (hours). Because body weight is a direct multiplier, heavier individuals burn more calories doing the same activity — the calculator accounts for this automatically, unlike generic calorie-per-activity charts that assume a fixed reference weight.

This calculator covers 15 activities common to Indian fitness culture — from walking and running to badminton, cricket, and skipping. It is the natural complement to the Calorie Calculator and TDEE Calculator: while those tell you how many calories your body needs per day, this one tells you how many your workouts consume.

How to use this Calories Burned calculator

Enter your Body Weight in kg — the formula scales directly with weight, so accuracy matters. Weigh yourself in the morning for a consistent reading.
Select your Activity Type — choose the activity closest to what you did. The MET value of the selected activity is used in the calculation.
Enter your Duration in minutes — be honest about actual active time, not total time in the gym (which includes rest periods).
Read Calories Burned — use this figure in your daily food tracking to understand your net calorie balance.
Check Fat Equivalent — a useful motivational output showing the fat mass impact of your session in grams.

Formula & Methodology

Calories Burned = MET × Weight (kg) × Duration (hours)

Where:
- MET = Metabolic Equivalent of Task for the selected activity
- Weight = body weight in kilograms
- Duration = exercise time in hours (minutes ÷ 60)

Calories Per Hour = MET × Weight

Fat Burned (g) = Calories Burned ÷ 7.7

(1g of adipose tissue ≈ 7.7 kcal; adipose fat is ~87% triglyceride + 13% water and protein)

Worked example:

70 kg person, jogging at 7 km/h (MET = 7.0), for 45 minutes:

- Calories = 7.0 × 70 × (45 ÷ 60) = 7.0 × 70 × 0.75 = 367.5 kcal
- Calories/hour = 7.0 × 70 = 490 kcal/hr
- Fat Equivalent = 367.5 ÷ 7.7 = 47.7 g of fat

Assumptions: MET values are from the Compendium of Physical Activities (Ainsworth et al., 2011). The formula assumes moderate fitness level and does not account for altitude, temperature, or individual metabolic variation. Actual calorie burn may vary by ±15–20%. Post-exercise calorie burn (EPOC) — especially relevant for HIIT — is not included in this estimate. Use the BMI Calculator to check your weight classification alongside your exercise planning.

Frequently Asked Questions

How does the calories burned calculator work?

The calculator uses MET (Metabolic Equivalent of Task) values — standardised measures of how much energy an activity requires relative to rest. Calories burned = MET × your body weight in kg × duration in hours. A MET of 1 equals rest; running at 9 km/h has a MET of around 9.8, meaning you burn 9.8 times more energy than at rest. The formula is validated across thousands of studies and is used by fitness trackers worldwide.

What is MET value and how is it used?

MET stands for Metabolic Equivalent of Task. A MET of 1 represents the energy expenditure at rest (roughly 1 kcal/kg/hour). An activity with a MET of 5 burns 5 times the resting energy per unit of time. The Compendium of Physical Activities, maintained by researchers at Arizona State University, lists MET values for hundreds of activities. This calculator uses those validated MET values to estimate calorie burn for the activities listed.

How many calories does 30 minutes of running burn?

A 70 kg person running at 9 km/h (MET ≈ 9.8) for 30 minutes burns approximately 343 kcal. At 11 km/h (MET ≈ 11.5), the same person burns about 403 kcal. Heavier individuals burn more because the formula is directly proportional to body weight — a 90 kg person running at 9 km/h for 30 minutes burns approximately 441 kcal.

How many calories does walking burn?

A 70 kg person walking at 5 km/h (MET ≈ 4.3) for 30 minutes burns approximately 151 kcal. At a slower pace of 3.5 km/h (MET ≈ 3.5), they burn around 123 kcal for the same duration. Walking is an excellent low-impact activity for those returning from injury or beginning their fitness journey — combine with calorie tracking using our [Calorie Calculator](/calorie-calculator/).

How many calories does badminton burn?

Badminton (MET ≈ 5.5) burns approximately 193 kcal per 30 minutes for a 70 kg person. It is one of the most popular sports in India and burns significantly more calories than walking, making it an excellent recreational fitness activity. Competitive singles play at higher intensity can approach MET values of 7–8.

Does body weight affect how many calories you burn?

Yes — heavier people burn more calories for the same activity and duration because they have more mass to move. The MET formula scales linearly with body weight: a 90 kg person burns 90/70 = 28.6% more calories than a 70 kg person doing the same activity for the same time. This is why calorie burn estimates from online charts (which often assume a fixed 70 kg reference person) may not be accurate for you.

What does the fat equivalent burned output mean?

Fat burned (g) = Calories burned ÷ 7.7 kcal/g. This uses the fact that one gram of body fat (stored as adipose tissue, not pure triglyceride) contains approximately 7.7 kcal of energy. It gives you an intuitive sense of how much fat mass is mobilised by the exercise session. Note that exercising does not mean you are burning only stored fat — your body uses a mix of carbohydrates and fat depending on intensity, and overall calorie balance across the day determines fat loss.

How many calories burned to lose 1 kg of fat?

1 kg of body fat contains approximately 7,700 kcal. To lose 1 kg, you need a cumulative deficit of 7,700 kcal — through exercise, diet, or a combination. A 30-minute jog burning 300 kcal per day, sustained for 25 days, would theoretically burn through 1 kg of fat if all other factors remain constant. In practice, combine exercise with dietary adjustments using our [Calorie Calculator](/calorie-calculator/) for faster progress.

Is HIIT or steady-state cardio better for burning calories?

HIIT (High-Intensity Interval Training) burns more calories per minute during the session and creates an after-burn effect (excess post-exercise oxygen consumption, or EPOC) that elevates calorie burning for hours after the workout. Steady-state cardio (jogging, cycling) burns fewer calories per minute but can be sustained longer and is lower impact. Both have similar total calorie burn when matched for total effort. HIIT is better for time efficiency; steady-state is better for recovery and sustainability.

Why does my fitness tracker show different calories burned?

Fitness trackers estimate calories using heart rate data, accelerometer readings, and proprietary algorithms — not MET values. These can be more personalised (especially if calibrated to your resting heart rate) but also more variable. MET-based calculations like this one are a standardised estimate useful for planning and comparison. Actual calorie burn varies by fitness level, metabolism, ambient temperature, and exercise technique. Treat any calorie burn figure as an estimate within ±15–20%.

Should I eat back calories burned during exercise?

Whether to eat back exercise calories depends on your goal. If you are targeting a specific net calorie deficit (calories consumed minus exercise calories), then yes — eating back some exercise calories helps maintain your intended deficit without over-restricting. If you track total daily energy expenditure via a TDEE-based approach (where activity is already factored in), do not eat back exercise calories — it creates double-counting. Check our [TDEE Calculator](/tdee-calculator/) to understand which approach your current plan uses.
